LEE, Guihan; CALDERON-UBAQUI, Victor  and  SACSAQUISPE-CONTRERAS, Sonia. Bacteria in contacting surfaces during intraoral radiographies procedures. Rev. Estomatol. Herediana [online]. 2016, vol.26, n.1, pp.4-12. ISSN 1019-4355.

Objective: Determinate the presence of bacteria through a microbiological analysis of contacting surfaces in a radiology service from the operator during the taking and process of intraoral radiographies in different moments of the day. Materials and methods: A sample was taken from nine surfaces of the oral radiography service. Samples were taken with a cotton stick swap with Triptic Soy Broth (TSB) in two different moments by the same investigator; at beginning and that the end of activities. The samples were inoculated and incubated in three different cultivar measures (Plate Count Agar, Sheep Blood Agar and Cetrimide Agar) and also Gram stein was realized. Results: A high concentration of bacteria (4180 UFC/mL) and fungus was found in the oral radiology service. The coccus gram-positive was most frequently found microorganism and bacillus gram-negative was poorly found microorganism in this study. Conclusions: A high of contamination with bacteria was found in the oral radiology service. At the end of activities of the day, decrease the quantity of bacteria, but increase variety of bacteria.
